Solinst’s Model 408 Double Valve Pump (DVP) is a pneumatic drive pump designed to provide consistent, reliable, and accurate samples. The 408 DVP is field serviceable, requires no bladder replacement, comes in varied sizes and materials with varied flow rates, and offers higher pumping rates than would be obtained with the Bladder Pump. Suitable for regular or low flow sampling, the 408 Double Valve Pump can also be equipped to operate at depths up to 2000 feet (600 meters) with proper equipment.

The Model 408 Double Valve Pump was designed to be easily accessible, allowing for easy replacement and swapping of parts. It can be easily decontaminated without need for specialized field tools. Due to similarity in parts and simple installation the 408 DVP can be converted easily to a bladder pump. Portable models can easily be prepared and deployed, and the 408 DVP is cart or reel mountable. The 408 DVP also delivers high flow rates, relative to a range of conditions (example: 3.3 l/min from a 1.66″ x 2′ DVP, 150 feet below water grade, at 100 psi with 1/2″ OD drive and sample lines).
